Soft Measurement of the Cell Concentration Based on SVM

The process of Pichia pastoris fermentation has a long period and less offline data . The cell concentration and some other important variables can not be measured on line.The soft sensor modeling at present is mainly the artificial neural network (ANN).This paper introduces the Support Vector Machine (SVM). Select fewer off line data and establish soft sensor modeling about cell concentration.Compared with the BP neural network prediction model, Simulation experiment proves that the support vector machine has better prediction effect and generalization ability. template.
